PATE T or ice This invention relates to ans-anchoring device. An objectof the invention is the provision of a device for anchoring rods inwhich a plurality of anchoring means are supported by pivotally mountedarms from a base member which is connected to the rod .to be anchored.

Another object of the invention is the provision of an anchoringdevicewhich includes a base member and arms radiating therefrom andpivotally connected .to said base member, the upper freeiend of the armsadapted to pivotally support anchoring members which are elongated anddished, the inner free ends of the anchoring means being engageable witha tamping element for forcing the anchoring members supported by thearms from a substantially vertical position to a substantiallyhorizontal position so that when concrete or other material is filledinto the hole in which the anchoring device is located, the device willbe held against movement.

A further object of the invention is the .provision of an anchoringdevice provided with a base member from which project arms removablyconnected with the base member, the upper free endsof thearms beingremovably connected'with elongated dish-shaped anchoring members whichare movable outwardly and supported by th'earms from the .axis of thebase member andadapted to.

be .forced through the walls of .a hole .or pit which the anchoringdevice is placed.

This invention will bebest understood from a consideration of thefollowing detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to beunderstood-that the invention is not confined to the disclosure, beingsusceptible of such changes and modifications as define no materialdeparture from the salient features of the invention as expressed in theappended claims.

or supporting for the anchoring members.

Figure .8 is .a fragmentary vertical section showing a'pocketl H I vReferring'more particularly to the drawing, .10 indicates a .circularbase member having .a centralpassage 11 into which is threaded, as shownat l2, the lower end of a 13 which is adaptedto ,be anchored inposition. Nuts 14 and Y15 rigidlysecure the rod to the base member.

Arms 1 6 project radially from the base member 10 and .any number of thearms maybe employed which will vbe suitable for the particu- .lar work.-:Ihese .arms are provided with reinforcing ribs 1.7 located at right:angles to a pair of the :opposite faces =of thearms. These ribsareformed integrally with the arms. The lower end .of each :arm .lfltissubstantially circular as shown atilli. Upon the opposite faces of thearm and adjacent the circular portion 18 are lugs .1 9.' These lugs havetheir opposite ends rounded, .as shown at .20, with the side edgesflattened as shown at 21. r .The inner .end 25 ;.of .each of a pluralityof pockets-which are formed in the base .member 10 is rounded to conformto the roundedportion 18 of the arm 16. A side wall 26 of the pocket isinclined upon which the outer edge of the arm 16 rests when the arms arein extended position. The mouth of the pocket is sufficiently wide thatthe lower ends of the arms 16 may be inserted within the pockets. Theportion of the'Ipoc-ket just described is the central portion in whichthe rounded portion 18 of the arm is located.

.At each .side of the central portion a lip .27 L

is provided which is adapted to engage the upper rounded portion 20 ofthe lugs 19 to prevent the lower ends of the arms from escaping from thepocket when said arms are in a substantially vertical position as shownin Fig. 3. Upon each side of the central portion of the pocket andadjacent the periphery of the base member 10 are provided flanges 30which engage the portions 31 of the lower end of the arm 16 and therounded portions 20 of the lugs 19 for aiding in maintaining the arms inthe pocket in connection with the lips 2'7. The space 27 between the endof each lip 27 and the free edge of the flange 30 is sufficient topermit the lugs 19 to pass into the pockets when the arms are inclinedoutwardly from the rod 13, the lips 27 and the flanges 30 being inco-operative engagement with the lug 19 to prevent the base member 10from dropping off the arms when the rod 13 is lowered into the pitformed in the ground.

The upper ends of the arms 16 are constructed in a manner similar to theconstruction at the lower ends and the pockets formed in elongateddished anchoring members 36 are somewhat similar to the pockets formedin the base member 10.

Referring more particularly to Figs. 3, 5, and 6, it will be seen thatthe upper extreme ends of the arms 16 are rounded, as shown at 37, andthis rounded portion rides upon the circular portion 38 of the pocket 39formed in a boss 40 at the underface of each elongated member 36. A pairof flanges 41 and 42 project inwardly from the walls of the centralportion and these flanges which are located upon opposite sides of therounded portion 37 of the arms 16 lie in fiat contact with the flatfaces of the upper end of the arm.

Lugs 45 are formed integrally on the opposite flat faces of the upperend of the arm 16 and these lugs are adapted to ride in the curvedportions 46 and 47 of the respective flanges 41 and 42. The oppositeends of the lugs are rounded as shown at 48, and are adapted to ride onthe curved portions just mentioned. The upper ends of the lugs areadapted to be located between the straight edges 50 and 51 of theflanges 41 and 42 when the elongated members 36 are in an operativeposition, as shown in Fig. 4.

A shoulder 52 is formed in the boss 40 and is adapted to engage an edgeof the arm 16 when the member 36 is in inoperative position as shown inFig. 3. By this construction the members 36 are pivotally connected withthe arm 16 but may be readily removed from the arms when desired.

A tamping member 55 has a radial slot 56 which is adapted to receive therod 13. The tamping member is provided with an eye 57 to which a chainis secured for removing the tamping memher after the anchoring device isin position. The inner face of the'tamping member has a comically-shapedportion 58 for guiding the inner rounded ends 59 of the members 56toward an annular groove 60 formed beneath a flange 61 of the tampingmember 55.

Each of the members 36 are elongated and are dished so that the outerfaces of said members will present a hollow portion to the ground whenit is forcedthrough the walls of the well 35, as shown in Fig. 4. Theouter extreme ends of the members 36 are pointed, as shown at 62, sothat said members may be forced through the side walls of the pit. V

The operation of inserting the device in the pit 35 in anchoringposition is as follows: The arms 16, as shown in Fig. 3, are moved to asubstantially vertical position so that the anchoring members 36 willincline at a slight angle to the vertical with the rounded inner ends 59of said members being engaged within the annular groove 60 of thetamping head 55.

A spring member 65 is held in place by the nut 14 on the base member 10and is adapted to engage the arm 16 tending to force the arms outwardly.The anchoring device is let down into the pit and the tamping head 55 isforced downwardly whereby the members 36 will be forced outwardlythrough the side wall of the pit 35 and these members are guided intheir outward movements by the knee action of the arms 16.

When the tamping element 55 has moved the arms to the proper positionthe chain connected to the eye 5'7 is elevated, thereby raising thetamping member. Due to the slot 56, the tamping member may be readilyslid ofi of the rod 13. The pit is then filled with concrete or anysuitable material for securing the anchoring device in the pit.

I claim:

1. An anchoring device comprising a base member, a rod secured axiallyof the base member, radiating arms pivotally and removably connected tothe base member, an elongated dished member for each arm, means forpivotally and removably connecting theouter ends of the arms tointermediate portions of the dished members, the inner ends of thedished members being reduced and rounded, and a removable tamping memberhaving an annular groove at the inner face thereof to receive therounded ends of the dished members.

2. An anchoring device comprising a base member, a rod secured axiallyof the base member, radiating arms pivotally and removably connected tothe base member, an elongated dished member for each arm, means forpivotally and removably connecting the outer ends of the arms tointermediate portions of the dished members, the inner ends of thedished members being reduced and rounded, a spring member secured to thebase member and provided with fingers tending to force the arms radiallyoutwardly, a tamping head having a groove to loosely receive the innerends of the dished members, said head having a central opening and aradial slot extending from the opening to provide for the removal andthe application of the tamping head to the rod and dished members.
